, skilled in the Be itknownfthat I, HERMAN A. DAVEN- PORT, a citizen of theUnited States, residing at Brockton, inthe countyof Plymouth and State ofMassachusetts, have invented certain new and useful Improvements in Sole-Pressing'Forms; and I do hereby declare the following to be a full, clear, and exact description of the invention,"such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for shaping larly to the pressing forms employed in connection with machines of this type which shape the outsole to enable it to be firmly The object of the present invention is to provide an improved pressing form which shapes the Outsole preliminary to the permanent securing of the sole to a lasted shoeV to enable the outsole to be securely united to the lasted shoe. i

With this object in view a feature of the invention consists in then provision of a pressing form having a central pressing member, an outer pressing member surrounding the central member and arranged to yield with relationgto the central member when pressure is applied to the sole to form an indentation in that portion of the sole engaged by. the central member.

'Further' features of the invention consist in certain novel features of construction, combinations and Iarrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those scription.

`In the accompanying drawings illustrating the preferred form of the invention;

AFigure 1 represents a sectional view of a portion of a pressing form in its normal'position; Fig. 2 is a view similar to Fig. l

lshowingthe form with the shoe located this portion of the sole shall engage and be `united with the instale. this feature can be readily appreciated whenv shoe soles and more particu-v art from Vthe following de- 4with the insole with The importance of it is understood that the upper of a lasted V,shoe forms an upstanding projection extending around the'margin of the shoe and as the outsole is laid'over this projection a hollow is left in the interior of the shoe which must be filled:` This feature may -be also advantageously employed in shoes where no insoleis used, but in which the upper is secured directly to a single sole.

In the illustrated embodiment of the invention an indentation is formed in the central portion of the heel seat of the sole, thus forcing this portion of the sole into contact with the. insole to firmly unite thetwo vat this point. In existing methods of manufacture it is customary to temporarily secure this portion of the Outsole in place by a fastening which is driven through the outsole'and insole into the last and with the present improved construction the employment of this temporary fastening is dispensed with. 'The illustrated embodiment of the invention is shown in connection with a pressing form of the type disclosed in the patent to Davenport, N o. 942,133, December 7, 1909. Thisl pressing form consists of a rubber pad 1 supported upon a series of pad blocks 3, which in turn are supported upon mechanism to equalize the pressure exerted over the entire shoe sole.

As illustrated clearly in Fig. 2 of the drawings, the pressing form is arranged to operate upon a'welt shoe having an insole 5, a shank stiii'ener 6, a'counter-portion 7 and an outsole 8. In the present invention the outer sole is pressed into engagement whlch is seated in a recess 12 formed in the pad. block, and extends upwardly through a slot formed in the rubber pad 1. It will be noted from an inspection of Fig. l that the top of the plug is normally positioned below the pressing surface of the pad, thus causing the pad to first engage with and clamp the Patented Mar. 7, 191e.

y a plug indicated at 10 sole to the shoe throughout its entire area,

after which a further pressing movement brings the end of the plug into engagement the outer sole and presses a portion of the sole into" engagement with the insole, as shown clearly in Fig. 2. In order to facilivtate the relative movement of the plug and pad and to allow the pad to be compressed the shoe into the pad Apressure andk moves 'to vary the vthe plug with pad and to this.

ut the plug, them-11s of' the slof are- 14. and the upper endy 15 of the when the rubber pad is compressed it crowds in about the upper and lower ends of the -as shown clearly in. Fig. '2. It will lug be observed that the plug 10 engages with the' surface of the sole before the complete pressure has been applied and' that afterl this engagement of the plug with the-sole a portion o the pressure is transmitted to the unyielding plug. This action substantially prevents the rounding` over'of the ex.

tension edge of the outsole at the heel seat, as with this type of pressing form before the pressure becomes great enough to sink the plug 10 takes the the. pad block vat the eel seat downwardly, equalizing the pressure over the entire shoe sole.

Under various conditions it isA desirable normal position of the end of relation to the surface of the end the plug isrovided with a lbase member 17 and a ca'p1 'adjustan ins ction of Fig. 1, the base member is provi ed with a lower portion which fits closely within the recess 12, and a reduced threaded portion 20` which engages withV a threaded recess 21 `formed in the cap.- In order to lock the parts in their adjusted position the threaded portion 20'is provided v the 23 is threaded transverselyl in the cap,

screw projecting into, the slot end of the set l l to prevent a relative rotation of theA cap and base member, as shown clearl1 in' Fig' 4.
